1 Claim. (Cl. 240-3) This invention relates to a combined floodlight,floodlight shade and bracket therefor.

It is an object of this invention to provide a novel combination of afloodlight, a floodlight shade and bracket therefor of the kind to bemore particularly described hereinafter by the use of which the lightemanating from the shade may readily be directed in any desired direction from the source of light.

Another object of this invention is to provide a combination floodlightand shade having rounded internal corrugations which will replace theneed for a lens to properly difluse the light rays being projected fromthe shade to a certain area to properly focus the light rays.

Still another object of this invention is to provide a floodlight andbracket of this kind having a pair of correlated half socket sectionsfor attachment to an end of a shade, each socket section having a partof a serrated pivot section formed integrally therewith from which theshade may be pivotally directed.

Another object of this invention is to provide a combined floodlightshade and shade holder therefor made of identically the same material,so that the unit may be easily and readily constructed at a substantialsaving in the cost of manufacture thereof both to the manufacturer anduser, and at the same time providing for an improved novel and usefulfloodlight shade.

Other and further objects and advantages of the invention will behereinafter described and the novel features thereof defined in theappended claim.

In the drawings:

Figure 1 is a side elevation of my improved floodlight shade and brackettherefor constructed according to an embodiment of my invention.

Figure 2 is a rear elevation, partly broken away, of my invention.

Figure 3 is a front elevation of my invention with the shade removed.

Figure 4 is a longitudinal section of my invention with a shade attachedthereon.

Figure 5 is a fragmentary longitudinal section taken on line 55 ofFigure 1.

Figure 6 is a fragmentary transverse section taken on line 6-6 of Figure1.

Figure 7 is a fragmentary detailed section taken on line 77 of Figure 6.

In the structure of floodlights and reflectors therefor, there has beenconsiderable difliculty in assembling the reflector and bracket thereforand I have manufactured this invention with that thought in mind toproduce a floodlight and bracket therefor which may be made of asubstantially unitary structure, or at least cast from the same materialso that both the floodlight reflector and bracket therefor may be madeat the same time and of the same material both as a saving to themanufacturer and a resulting saving to the buyer.

Referring now more particularly to the drawings, the numeral 10designates generally a floodlight reflector and bracket therefor havinga pair of floodlight reflector sections 11 secured together after theyare formed to provide a complete conical base section of the reflectoron the bracket. Each of the floodlight reflector sections 11 has aflange 12 extending longitudinally thereof on the opposite side edgesof'the reflector which are secured together by bolts 14 and providethereby a complete base or socket for a floodlight reflector.

A light sealing and locking flange 15 is provided on one of the flanges12 for-completely sealing the light in the reflector and these flanges,the member 1 and flange 15 provide a substantial guide 16 for engaging aflange 12 of another segmental reflector section.

The reflector thus formed will provide for a socket for engaging about abulb socket 17 having an electric light bulb 18 threaded therein andspaced longitudinally from the built-up reflector of my invention.

There is an attaching arm 19 formed integral with and extendingdownwardly and outwardly from one of the 4 of the drawings. Thisattaching arm 19 has an opening 29 extending along the length thereofwith a flat disc 21 on one side of the arm 19. This flat disc 21 has acenter opening 22 therein from which radiate the radially extendingserrations 24 for the angular attachment of the reflector to theattaching arm 18 in a manner to be more particularly describedhereinafter. V

The base 25 includes an outer cylindrical base socket 26 open at theupper end thereof and substantially closed at the lower end with abottom Wall 27, having a central axial opening 28 therein for thepurposes again to be more particularly described hereinafter.

A second or inner socket 29 is enclosed Within the outer base socket 26,the inner and outer sockets of the base being held together and securedtogether against rotation or sliding movement by a transverselyextending bolt 34 which extends transversely through the attaching arm29. Another bolt 30 extends through the opening 22 and upper flattenedend of the cylindrical inner sleeve of the inner socket 29 as mostclearly indicated in Figure 6 of the drawings. An eye 31 is provided onone end of the bolt 30 while the other end of the bolt which isextensible through both the attaching arm 19 and upper flattened end ofthe inner base sleeve or socket 29, is threaded for attachment of afastening element or nut 32 thereon when the serrations on the attachingarm 19 and the serrations carried by the upper flattened end of theinner socket 29 are meshed together for securing engagement.

The bolt 34 is engaged through both the inner and outer base sockets 26and 29 so that the base sockets may be secured together in any selectedposition relative to each other.

One end of the bolt 34 is enlarged as indicated by the reference numeral35.

This upwardly extending flat end of the inner socket 29 is provided witha plurality of radially extending serrations 37 which are engageablewith the serrations 24 of the disc 21 on the attaching arm 19 uponfastening engagement of the bolt 30, with the eye thereon, when thefloodlight has been pivoted to its desired relation with the base.

An opening 28 is formed in the lower transverse wall of the outer basesocket 26 through which the electric lead for the floodlight may beengaged when the floodlight and bracket therefor are placed inoperation.

A light shade 39 may be attached to the floodlight, although such ashade would not necessarily be required for the use of this floodlightand bracket therefor.

An inner bead 40 is formed on the more restricted end of thesubstantially conical shade 3d engageable in a groove 41 about the outerend of the floodlight-engag ing socket described above.

The shade 39 is substantially as a reflector having a in the drawings.

Howev'en's'uch a shade 39 would not be necessary for the proper ilseofthis floodlight and bracket therefor, as the light emanating fromthelight bulb 18 and floodlight sections 11 may be so dit'fusedthat theshade 39 may be unnecessary.

, The base 25 has a plurality of radially outwardly extending legs 44with the foot 45 on the outer end thereof spaced frornthe outer basesocket 26 as clearly indicated These legs and feet provide for theattachment of the floodlight and bracket where and as desired, althoughthe particular arrangement of the base and floodlight are particularlyadapted for use on a flat supporting member, not shown in the drawings.

While the specific details of one embodiment of this invention have'beenherein shown and described, the invention is not confined thereto aschanges and alterations maybe made without departing from the spirit andscope thereof as defined in the appended claim.

I claim:

In a floodlight, a base formed of a cylindrical outer wall, a pluralityof radially extending arms extending from said outer wall, an innercylindrical wall disposed in said outer wall, a bolt securing said wallstogether, an upstanding flat hollow arm rising from said inner wall,

an upper combined reflector and socket, a depending hollow arm extendingfrom said combined reflector and socket, said depending hollow armterminating in a hollow circular member, radial teeth carried by saidcircular member, radial teeth carried by said flat hollow arm, saidcombined reflector and socket including a lower semicylindrical memberintegral with said depending arm, lateral flanges carried by saidsemi-cylindrical member, an upper complementary semi-cylindrical member,lateral flanges extending from said upper semi-cylindrical member, aninwardly projecting locking flange carried by one of said latter namedflanges, one of' said first named flanges engaging between said lockingflange and said one flange of said upper semi-cylindrical member, a boltextending through the other one of said first and second named flanges,semi-conical projections extending from said semi-cylindrical membersand each projection formed with a groove on the inner side thereof andadjacent the large outer end, and a shade carried by said projections,said shade including an inner bead seating in said grooves.
